Dr. Jim Liu, a cardiologist at Ohio State University Wexner Medical Center who was not involved in the study, noted that there is conflicting data on whether fish oil and omega-3 fatty acids help reduce the risk of cardiovascular disease.

“Previous studies have shown that certain combinations of fish oil can help reduce cardiovascular disease in people with high triglyceride levels and a history of cardiovascular disease,” Liu noted.
“Overall, this is another study that reminds us that there is still a lot to be explored when it comes to fish oil and heart disease.”
Nutritionists weigh risks and benefits
Tanya Freilich, a registered dietitian who goes by The Lupus Dietitian in Charlotte, North Carolina, was not involved in the study but offered insight.
